Mastery (55 page)

In the course of his deep thinking, he came up with two important principles that would guide him further. First, he determined that his original intuition had to be correct—the laws of physics had to apply equally to someone at rest as to someone traveling at a uniform speed in a spaceship. Nothing else would make sense. And second, that the speed of light was a constant. Even if a star moving at several thousand miles per hour emitted light, the speed of such light would remain at 186,000 miles per second and not any faster. In this way he would adhere to Maxwell’s law on the invariable speed of electromagnetic waves.

As he contemplated these principles further, however, another paradox emerged in his mind in the shape of yet another image. He imagined a train speeding along a track with its lights beaming. A man standing on the embankment would see the light of the beam moving at the expected speed. But what if a woman were running toward or away from the train on the tracks? The woman’s speed relative to the train would depend on how quickly she was moving and in which direction, but wouldn’t it be the same with the light beam? Certainly, the light beam from the train relative to the woman would travel at a different speed if she were running away or running toward it, and the speed of this beam would be different from the speed relative to the man on the tracks. This one image seemingly called into question all of his guiding principles up until then.

For months he pondered this paradox, and by May 1905 he had decided
to give up the entire matter. It seemed beyond solution. On a beautiful, sunny day in Bern, he walked with a friend and colleague from the patent office, explaining to him the dead end he had reached, his frustration, and his decision to give up. Just as he said all of this, as Einstein later recalled, “I suddenly understood the key to the problem.” It came to him in a grand, intuitive flash, first with an image and then with words—a split-second insight that would forever alter our own concept of the universe.

Later Einstein would illustrate his insight through the following image: Suppose a train is moving past an embankment at a constant velocity. A man stands in the center of the embankment. Just as the train moves by, lightning strikes simultaneously at two equidistant points, A and B, to the right and left of the man. Suppose there is a woman seated in the middle of the train, who is passing just in front of the man on the embankment as the lightning strikes. She will be moving closer to point B as the light signal travels. She will see it strike ever so slightly ahead of the lightning at point A. What is simultaneous for the man on the embankment is not so for the woman on the train. No two events can ever be said to be simultaneous, because every moving reference frame has its own relative time, and everything in the universe is moving in relation to something else. As Einstein put it, “There is no audible tick-tock everywhere in the world that can be considered as time.” If time is not absolute, then neither is space or distance. Everything is relative to everything else—speed, time, distance, and so on—except for the speed of light, which never changes.

This was called his theory of Simple Relativity, and in the years to come it would shake the foundations of physics and science. Several years later, Einstein would repeat the exact same process for his discovery of General Relativity and what he called the “curvature of spacetime,” applying relativity to gravitational force. He again began with an image, a thought experiment that he pondered for close to ten years, leading to his breakthrough theory in 1915. From this theory alone he deduced that the course of light rays must be bent by the curvature of spacetime, and had gone even further to speculate the exact bend of the arc for rays of starlight grazing the sun. To the astonishment of scientists and the public alike, during the solar eclipse of 1919, astronomers were able to precisely verify Einstein’s speculation. It seemed that only someone with superhuman brain capabilities could deduce such a measurement simply through abstract reasoning. The fame and reputation of Albert Einstein as a freakish genius was born at that moment and has remained ever since.

Although we like to assume that a genius like Albert Einstein had powers far beyond our capabilities, his great discoveries depended on two
very simple decisions he made as a young man. First, at the age of twenty he determined that he would be a mediocre experimental scientist. Even though a heavy immersion in mathematics and experimentation was the conventional route in physics, he would go his own way—a daring decision. Second, he would consider his primal distaste for authority and conventions as a great strength. He would attack from the outside and unburden himself of all the assumptions that were torturing scientists in relation to Newton. These two decisions allowed him to play to his strengths. A third factor can be identified as well: his love of the violin and the music of Mozart. To others who would marvel at his feel for Mozart, he would reply, “It’s in my blood.” He meant that he had played this music so often that it had become part of him, his essence. He had an inside understanding of the music. This would become the unconscious model for his approach to science: he would think himself inside complex phenomena.

Although we tend to imagine Einstein as the ultimate abstract thinker, his way of thinking was remarkably concrete—almost always in terms of images that related to the everyday objects around him, such as trains, clocks, and elevators. Thinking in this concrete way, he could turn a problem over and over in his mind, consider it from all angles while walking, talking to others, or sitting at his desk at the patent office. He would later explain that imagination and intuition played a far larger role in his discoveries than his knowledge of science and mathematics. If he had any qualities that were extraordinary, they were his patience mixed with his extreme tenacity. After what can only be considered as well beyond 10,000 hours of contemplation of one problem, he reached a transformation point. The various aspects of a supremely complicated phenomenon had become internalized, leading to an intuitive grasp of the whole—in this case, the sudden image that came to him revealing the relativity of time. His two theories of relativity have to be considered as perhaps the greatest intellectual feats in history, the fruits of intense labor and not of some extraordinary, inexplicable genius.

There are many paths to mastery, and if you are persistent you will certainly find one that suits you. But a key component in the process is determining your mental and psychological strengths and working with them. To rise to the level of mastery requires many hours of dedicated focus and practice. You cannot get there if your work brings you no joy and you are constantly struggling to overcome your own weaknesses. You must look deep within and come to an understanding of these particular strengths and weaknesses you possess, being as realistic as possible. Knowing your strengths, you can lean on them with utmost intensity. Once you start in this direction, you will gain momentum. You will not be burdened by conventions, and you will not be slowed down by having to deal with skills that
go against your inclinations and strengths. In this way, your creative and intuitive powers will be naturally awakened.

In thinking back to her earliest years in the 1950s, Temple Grandin could only recall a dark and chaotic world. Born with autism, she could remember spending hours on the beach watching grains of sand pour through her hands. (For more on Grandin see

.) She lived in a world of constant terrors—any sudden noise would overwhelm her. It took her much longer than other children to learn language, and as she slowly did, she became painfully aware of how different she was from other children. Often alone, she naturally gravitated toward animals, particularly horses. It was more than just a need for companionship—she somehow felt an unusual identification and empathy with the world of animals. Her great passion was to go horseback riding in the country around Boston where she was raised. In riding horses, she could deepen her connection to them.

Then one summer, as a young girl, she was sent to visit her Aunt Ann, who had a ranch in Arizona. Temple felt an instant connection with the cattle on the ranch, and she would watch them for hours. What particularly intrigued her was the squeeze chute they would enter to be vaccinated. The pressure from the side panels of the chute was designed to help relax them while they were injected.

As far back as she could remember, she had always been trying to wrap herself in blankets or bury herself under cushions and pillows to somehow feel squeezed. As with the cows, any sort of gradual compression would relax her. (As is common for autistic children, being hugged by humans was overstimulating for her and induced anxiety; she had no control over the experience.) She had long dreamed about some kind of device that could squeeze her, and seeing the cattle in the chute she realized the answer. One day she begged her aunt to let her into the chute to be squeezed like a cow, and the aunt agreed. For thirty minutes she experienced what she had always wanted, and afterwards felt a complete calmness. It was at such a moment that she realized that she had some kind of strange connection to cattle, that her destiny was somehow tied up with these animals.

Curious about this connection, a few years later in high school she decided to research the subject of cattle. She also wanted to find out whether other autistic children and adults felt the same way. She could find very little information on cattle and their emotions or how they might experience the world; there was much more on autism, and she devoured books on the subject. In this way, she discovered an interest in the sciences; doing research allowed her to channel her nervous energy and learn about the world. She had tremendous powers to focus completely on one subject.

Slowly, she transformed herself into a promising student, which allowed her to gain admittance into a liberal arts school in New Hampshire where she majored in psychology. She had chosen the field because of her interest in autism—she had a personal, inside knowledge of the subject, and following this major would help her to understand more of the science behind the phenomenon. After graduating, she decided to pursue a PhD in psychology at Arizona State University, but when she went back to the Southwest and visited her aunt, she reconnected with her childhood fascination with cattle. Not really knowing why or what it would lead to, she decided to switch her major to animal sciences. For her thesis, she would focus largely on cattle.

Grandin had always done much of her thinking in visual terms, often having to translate words into images before she could understand them. Perhaps this was the result of the unique wiring of her brain. As part of the fieldwork for her major, she visited a couple of cattle feedlots in the state, and she was appalled by what she saw. It suddenly became clear to her that her propensity to think in visual terms was not shared by most others. How else to explain the highly irrational design of many of these feedlots and the remarkable lack of attention paid to details that were so visible to her eyes?

She would watch with dismay as the animals were herded through cattle chutes that were far too slippery. She would imagine what it must feel like to be a 1,200 pound animal suddenly sensing a loss of control on surfaces that were clearly too slick. The animals would bellow and stop in their tracks as they slid into one another, causing a sudden pileup. At one feedlot, almost all of the cows would stop at the same point; something in their visual field was obviously terrifying them. Didn’t anyone stop to consider what was causing this? At another feedlot, she witnessed the horrifying spectacle of cattle being herded onto ramps leading to a dip vat—a pool of water full of disinfectant to help rid them of ticks and parasites. The ramp was too steep and the drop into the water too great; some of the cattle would tumble upside down into the pool and drown.

Based on what she had seen, she decided to do a detailed analysis of the efficiency of these feedlots, and how they could be improved, for her master’s thesis. She now visited dozens of these sites, and each time she would stand close to the chutes, recording the reactions of the cattle as they were branded and vaccinated. On her own, she would approach the cattle and touch them. When she used to ride horses as a girl, she often could sense the mood of the horse just by the contact with her legs and hands. She began to experience the same with the cattle, as she would press her hands on their sides and feel their relaxing response. She noticed that when she was calm,
they would react to her in a calmer manner. Slowly, she was getting a sense of their perspective, and how so much of their behavior was guided by perceived threats that we could not necessarily notice.

It soon became obvious to Grandin that in the animal sciences department she was essentially alone in her interest in the emotions and experience of animals. Such subjects were considered beneath scientific interest. She persisted, however, in these lines of investigation—for her own sake and because she felt they had relevance to her thesis. She began to carry a camera with her on her tours of the feedlots. Knowing that cattle are very sensitive to any contrasts in their visual field, she would follow the course of the animals through the various chutes, kneeling and taking black-and-white photographs from their point of view. Her camera would pick up all kinds of sharp contrasts in their field of vision—bright reflections from the sun, sudden shadows, the glare from a window. It was clear to her that seeing these sharp contrasts is what caused the cattle to stop repeatedly in their tracks. Sometimes the sight of a suspended plastic bottle or a dangling chain would cause the same reaction—somehow these things represented dangers to them.
